Efficiency Issues and Solutions in Blockchain: A Survey

摘要

With the growing number of blockchain-based solutions in a few industries, we have moved to the next level of digital privacy. Meanwhile, several concerns related to transaction speed, data size, tracking information on public distributed ledgers faced to us. Time constraints and data overflow will lead to high financial expenses. In this paper, we address the efficiency issues of blockchain technology by reviewing recent significant work. First, we list the main challenges facing for efficiency. Then, we survey prior methods to handle efficiency issues studied by authors. Finally, we will discuss open challenges and conclude the work. This work can be helpful to determine future work directions.
